View of t e machine. of thel mechenisin for the friction weight neon the reel; and Fig. of the earn slide wir actuated rod which mi@ l The frame consists essentially of two side frame members 1-1, a horizontal transverse bar 2 secured to the side frame members,

and various transverse shafts hereinafter mentioned and tie rods 3, placed wherever necessary to tie the side members together and give the entire frame its required rigidity.

26 re resents the main actuating shaft from w ch all of the other parts of the machine receive' their motion. Secured to this shaft are two large gear'whe'els 27 which mesh with pinio/ns 28 on the shaft 29 which s driven b any suitable outside power.

The oscillating feed bar 10 is attached to the upper ends of arms 11, whose lower ends are pivoted upon a transverse shaft r1U. Two substantially vertical arms 32 are pivoted at their lower ends upon a transverse shaft 306, and they carry rollers 32',L which engage with cams 30 on gears 27, whereby said arms' 32 'are rocked forward and backward. Connecting rods 37 connect the arms 32 with arms 11, so that the latter 'are also.

rocked backward and forward. The connecting rods 37 are adjustable' in length, and they may be connected witlr'arms l1, at

various distances from the pivots of said arms, so that the throw of the feed bar may be egual to the required' distance between stays on the finished fence.

An oscillating gear segment-36 is pivoted to one of the side frame members l, and itis .given an oscillating movement by a crank 39 upon the main shaft 26, from which motion is transmitted to said segment by a connecting rod 38. The purpose oi4 this segment 'is to operate the stay twisters.' It engageswith a pinion 35, loosely mounted upon the twister shaft 34. rlhis pinion 35is periodi*` ically connected to the shaft 34 by means of a clutch which includes a jaw 38h, secured to the pinion 35, and a jaw 38 on' the end of a sleeve 40 which may slide upon, and .which has a tongue and groove connection with shaft 34. This sleeve has a circumferential lgroove for the reception of the fork 4 l on the end of a rod 42, which may slide back .and forth in one of the side frame members. A spring 47 tends to move this rod in the direction to disconnect the clutch members; while said rod is moved in a contrary direction by means of a lever 44 carrying on its end a friction roller 45, which engageswith a camshapcd suilace 32), on they gear'wheel 27.-I

Adiustalily secured to Lhc shaft 34 are a plurali( y of r cars 3?. hashing with the geared parts ol' the tuisteis 43,. These twisters are sha ird substantially like thoseshown in my said' prior patent; and each has, in addition to the geared part, a cylindrical part on which it turns; and a slot is formed in each one, extending: from end 'to end, and radially l inwai d from the peripiiciy to a point beyond thc centen-athis slot .being only very little wider than the diameter of the stay wires; Each twister is rotatably mounted in a slotted bracket 49. These brackets are adjustably securedito, and project below, the rear face of the transverse bar 2. Guide blocks 5 are also secured to the rear side of bar 2, and one of them is located between each adjacent pair of t\visters,their width being substantially equal to the distancel be.- tween said twisters. Each guide blockhas a hole '4 through its front wall, and a rearwardlyextended platform 53, in which is a groove 54, to receive'and guide the line wire NV whichis threaded through the hole 4. ca plate is secured lover said groove, to ho d the wire therein. Perhaps it might be more correct to-say that the groove54 is between the platform 53. and cap 55, because it may be in the former as shown in Fig'. 25, or in the latter as shown in Fig. 29.-

The rear edge of each guide 5 forms the fixed jaw 8 of a air,-the veritcallyy movable jaw 7 being the ower end of a lever 56 which ispivoted 0n a horizontal axis to block 5. These 'aws serve twoimportant functions. First t ey are the means whereby to'give the -line wires of the fence a sharp and apprcximately right angle crimp or bend at the point where the stay Wires are to embrace the line wires (see Figs. 29, 23, and 24). These crimps are very important character-7 istics of the fence, since they4 revent the slipping of the stays, and they a so allow the crimped line wires when the fence is erected, to expand and contract underv the iniiuence of va g temperatures, without damage.

contain respective y the horizontal grooves E and l" (see Fig. 29) in which the stay wires are guided across the machine, passing one ,above and one below the line wires. These grooves are alincd with Athe slots ,in the twisters so that the stay wiresare thereby guided through said twisters. T hesc grooves Eand F are formed in the proximate faces of hardened steel blocks C and l) which are let into the face of --the two jaws 7 and 8 wherein they are held by,` set screws 57. Each of these levers 56, which. carry the movable jaws has a segment geai on its up- ,per end; and these segment gears mesh with segment gears 58, secured upon a rock shaft 59 mounted on the bar 2. This rock shaft has an arm 60 attached to 'it at one sid of the machine. A connecting'rod 61 is pivoted to the end of this rock arm, und the lower end of the 'connecting rod is connected to a lever 62 which is )ivotcd at 63 to one ol' thc inner face of the adjacent gear 27. The. liront end of the lever 62 is loi-mcd wi'th the, weight 66 wlzich opere tes to muvo the lever l in 'that direction, which through the dcscribcd mechanism, will cause. the, movable Secon y, the enga ing faces of these jaws i sidefmembers :im is provided with a roller 64 Wluch'engages with the cam' 65' ou the -to thc shaft .one of said feed rollers 19 Vthrorgh the interniediateA pinion 1G?.

'engages in the circumferential groove in this sleeve 153, ulnle the other end oi the eos-ges? jaws to opeii,iv'hile the cani referred to moves l this lever in the opposite direction, and causes the jaws to close and thereby to crimp l the line vrires as stated. All of the line wires ass through wire straighteners 15 of familiar orin7 and then around grooved sheaves 16 secured upon a single shaft,-the purnose of these sheaves oeinfr to insure thefee( ing of an equal length oi each -vire into the inacliine. The straighteners rich ere provided with a set screY E7 supply th necessarytension to cause the wires to hug these sheaves closely. The two outside line wires are passed respectivelj.' through two winders a; and the intermediote line wires are threaded through the openings l in the i blocks 5 und then through the groove 53 and between the inns 7 cud All of the wires then pass through slot 125 in the feed har 10, and thence to the reel 12 upon which the nished fence will he Wound.

Two stay wires S are ted across the, ina l chine periodically in the grooves if] end lP hy i two pairs ci' groove rollers lo which are tipped at such an angle will enable rhein to deliver-the wires i'nto said grooves. lhe upper feed rollers are 7ooth mounted in a swinging trarne 2t) pivoted to the base in ulrich the ioiver rolls are journaled und the base is iixed to a suitable su port )rojecting laterally troni one ot' the side mein ers. 'lhc position ot' this swinging l traine and consequently the nosition of ,the up? r rollers with respect to the lower rollers; 1s determined by a set screw 21 u hich screws' down throi gh a yoke rigid with the hase against a part of said swinging traine.. 'l he feed rollers have attached to their slistts the interineshin pinion-s 1143. 'l-his stoy wire T" feeding mechanism 1s operated periodi by the lollovving inethsnisni, (ses lf 39, 40, and 41)- A beveled l'aecncd meshes with aheveled gear 104 attached to a shalt .105 mounted in a hearing 11e. A pinion 106 is rotatively mounted upon this shaft. This pinion. is driven hv the gear Z7 l A clutch is provided for connecting pinion E06 withl shalt 105. This is an ord'incry jew clutch, one port oi' which is on pinion 106, chile the other part 1.08 is the end of a sleeve having a tongue and groove sliding connection with shaft 105. A fork lever 111 lever engages with a cani 112 on the inner face of the adjacent gear 27, acts to @nove sleeve canse the clutch ifi understood that fed across the me and the internist crimped th further nun A spring 113 l in direction to engage. .tt will he the embrace of thc Winders. `'lhc windcrs are tubular, and are rotatabl.7 mounted in brackets 14 which are adjustaly secured to cross har 2. A rack har is associated with each winden--and this rack bar is vertically movable in adeen vertical groove in said bracket. rlhis raclr bar has two sets of teeth7 one of which engages with a pinion 76 'which lies in the same vented from moving axially, and which surrounds the Winder and has a tongue and groove connection therewith. The other set of rack teeth are engaged by a pinion 73 attached to a shaft 72 whereon is secured a pinion 71. Y teeth on the end of a lever 67. (sce Fig. 19). which is pivoted to an extension of bracket '14 and carries on one end a friction roller 69 which engages with a cam 7G on the shaft 25.

The stay Wires pass over each of the out side line. Wires and between it and a pawl '79 carried hy the Winder at the end thereof.

' his porvi is secured to a, short rock shaft S0 Whose axis is parallel to the axis of the Winder, and which is mounted in the head of' the Winder and a flan eA 81 secured to the Winder. Secured to this shalt 8() is an arm 82 carrying a friction roller 83 on its end.

This friction roller normally lies in Contact with the surface of a fixed cani 84 which lies adjacent to e. fixed cylindrical boss 85. This cam in sorne parts ot its periphery is of the-,seine diameter as this boss. A spring 89a acts to turn shaft 80 in that direction which turns up the pa-Wl 7 9, and which holds the friction roller 88 against the cani S4. Each of these Winders has an endvrise Inovenicnt as ivell'as a rotary movement. To produce this movement a fork lever 85 engages with a grooved collar Vsecured to the Winder tube. 'lhis erin 85 is attached to a rock shaft 85 to which is also attached a lever 87 Whose outer end hears against a cam 88 on one ot' the gears 27g-.a spring being provided to hold it in such engagement. As the Winder is turned, roller 83 rides up the cani Se and thereby rocks the rock shaft SO'So as to cause the pawl 79 to bear upon the stay wires. W hen this roller 83 has reached the highest pert of cam '84, the Winder has been moved forward, (that is to say toward the left as shown in Fig. 32) and this movement causes s like movement of the roller 83 which carries said roller over onto the cylindrical boss 85. The Winder mav now rotate several times until the out oil' ends of the stay Wires are ywound upon the outside line Wires. Thisiendwise movement of the twister has an effect of cau-sing the stay wires to Wind snirally-upon the line Wire to make a good looking coil.` Before the. Winder has ceased its rot-ation in the direction referred to, the pa'vvl 79 has passed out of engagement with the stay Wires. it is at this time cove, being thereby prelhis pinion is engaged hv gear position.

' automatically stopped.

feed bar 10 draws the finished fence along ont ot' the range of said winder; and thereafter the winder turns in the other direction as the deserihed parts return to their first lust'hel'ore the winders eonnnenee to move the cutter '300 is operated to sever the stay wires. and it consists ot a pivoted blade. secured to a rock shaft Z501, which is provided with an arm 301%. rl`his in turn is secured/to one end of a rod 304, the other end of which is attached to one end of a rock arm 305, mounted loosely upon theI rock shaft 306. A cam 307 upon the shaft 37 serves to raise and lower this arm and operate the. cutter so that its movements shall be timed to ent the stay wires at. the proper time. v

lt will readily he seen that the twisting of the stay wires tends to shorten them, and

hence it' the stay wires were tirst wound upon the outside wires of the fence, the outside wires would be pulled together and lient outot shape by the twisting, hence-the movements of the parts are so timed as to iirst open the wire bending `jaws 7, then operate the twisters and nearly complete the stay, and then to operate the winders and coil the wire about the outside wires. To further. insure that said outside wires will remain straigl-it, the vertically movable fork hars 05 are provided which when moved down, embraee the. two outside wires. These t'ork bars are mounted in brackets 9S, which :1re 'secured to bar 2. In the upper ends ot' the hars are horizontal slots 96. vInto each of these slots projects a lcrank pin 95 on disk 97 attached to a rock shaftmonnted in said bracket 9S. Crank arms 09 secured to the other end of these shafts are connected by a hai-99a. An arm attached to said har has a hole which reiieives the 'hent end 101 of a lever -100 which is pivoted to a iixed supportand engages with a cam 102 upon the main shat't. The iorlf. oars 95 are-inoved down over the line. wire once during every revolution ot the main actuating shaft and are maintained in their position locking the wires during the entire duration otthe twisting and -winding movements, when they must be raised to iernnt of withdrawing the fence hy means ot the mechanism provided for that purpose. I

The partsdeserihed operate in a natural sequence as follows: fter the jaws 7 have been closed down upon the line wire and the bends are formed therein, the stay wire feeding mechanism is started into action by l means ofjthe automatic clutch mechanism shown in Fig. 32. As soon as the stay wires are t'ed to the machine through guides, which lead them ahove the outside line wires to the winders, 11nd respertirely ahoye and below the intermediate wires, one on eaeh side of the angular hends therein, the stay wire. l'eed holding forks 95 have also l 'l`he holding forks 95 have by this time descended upon the ontside line wires, and hold them rigidly in place. The jaws 7 then open, and the twisters lorated between the bends in the line wires commence to rotate. These twisters make two revolutions, and when they have finished their work. the slots therein have been carried somewhat past the slots in the twister brackets as shown in Fig. 13 in whirl?. position it would not he possihle for the stays to be. withdrawnftheretrom. lt is nt'eessary for this reason that` a slight reverse 'nierement should he given the twisters so that' the slots ytherein shall register with the slots in the supporting brackets, whereby the stays can hepulled out from them. This untwisting movement is given to the twisters to allow for the natural tendency of the stays to nntwist a little, and so that the twisters will be in a position to release them when the natural untwisting process is completed. lf not permitted to untwist, the stay wires would hind in the twist-ers. Means are therefore required to t'urn the twisters hat-k slightlyto permit the Withdrawal of the stay wires, and to immediately turnhaek the ltwisters to thc diagonal position in -which they mustbe placed to receive the stay wires when they are fed across the machine. T his is accomplished hy means oi the erank anin 1,23 set in the disk 12-1 u ion the enteren-d of the twister shaft, upon tl Betweenthe end of the twister shalt and the adjacent gear 27 are the sliding itat-es or hars 115 and 11G, whose vertieal'edges 117 and 118I are adapted to he engaged by pins and 120 set in the inner side of the atijaeent gear 27, and with reversely inclined edges 121 and 122 ada'pted'to engage the pin -123 on the disk 124, one after the other. and

throw it first iu one direction and then in the other. Springs -serve to withdraw the hars instantly as soon as they arereleased'hy the pins u on the gear 27. The winding of the ends o the stay wiresu ion the outside line wires has been arcomplislied hetore this, and wen raised. and all is now in readiness tov withd the required distance between twoays so that another staycan be attached to the line wires. This is accomplished hy the reciproeating feed bar 10 and the parts carried thereby. T his feed bar is secured at' its ends 1e side ot" the traine.

Ill() by horizontal pivots to the upper ends of the f hars 11 and has a limited rocking motion on`- said pivots. A rod 127, secured to the feed bar, passes through an opening in a plate v127 secured to the. stationary bar 2, has t 1e effect of rotating the feed har ahoutits pivots sufficiently to oil'set its angular divergence from the horizontal due to the swinging movements of the arms 11,--and this maintains the lower edge l'tiof slot 12.3'in a suhstantially horizontal position at all times. liyoted upon the rear face of this teed har imi sores? i oi parvis 128 adapted to lrires upon the edge of the ie feed` bar,r one pawl for elr engaging extremities 129 itly serrated to' give 'setter 'hese pawls are `provided l upper extremities 130 whie i f forks 131 secured to the rook cn is mounted longitudinally fen bar. v extremity of this shaft are secured 13S uponthe upper end of which is a guide or box 134 for the rod 135, therein, and is secured at its rear Le the pin 136 which is rigidly atne extension 137 of one of the side This bar is provided with 1 135'1 end 135b (see Fig. 8), 'i respective lv engage with .the box 134,

t and forks thereon so as to as the feed bar reaches its forand to release themas the feed ts rearward position. The pres- .aivls 128 u on the Wires is first by means of the inner side of each 3 which is shown as a spring 13S, strong to give firm Contact but frei energia to Wedge the panl if the Tenir/nt of the fork should be too great. ssreivs 139 and 140 may be employed z nrias 141 upon the rook shaft, to limit @reine-nt of the forks. 'lhe moment wire is caught, however, under the it is automatically held thereby until d As soon as the rearii'ard moveoi the feed bar ceases the rock shaft 132 beek andl the forks release the ein vthe Wires.

To insure further regularity in the feed of all parts oi' looks 142 pivoted upon the lower Y non olf the feed bar and secured to a coinshaft 143 rise as the bar moves in g Idirection and engages the sta?1 iron. beneath, and continues to pui Yn there. until the feed bar s to s and begins ard motion, when the iiooks fall by i their former position beneath the el the stay Wires.

hooks are raised by means of a simple f dient, viz. A plate 144 upon the side bar either side of the machine, or one plate is Drovided with a curved edge 145, stands ly the arc of a circle described i il d ivotal point of the swinging arms in a boss 146 upon the rock shaft 14?, is

seeker. for a substantially vertical rock- 14,1 having a crank arm on its lower end ages this edge during the feeding,r oi" the feed bar, and tips un the, f z and arins thereon until said liooks the slay wires. This crank arm beyond plate 144 during the feeding The eleet is to swing the par/ls into Contact withV movement, Wherefore when the feed barbeins its return movement the books drop own through the action of gravity, as before stated. There is an inclined surl'aee 14S on one side of the plate 144 which engages said crank arrn andlswings it to the side of late 144 so that said plate will not swiner the shaft to carrv the hooks upward. A spring 149 returns 't ie said shaft 147 to the position when it will engage 'with edge of the plate 144, when the feed bar again swings in the feedi direction. Forks 15G mounted ad- `iustab y u on a shaft 151 mounted on -tlie feed bar, elo'av its axis, serve to aline the Wires and maintain them in a proper position for the pawls to seize them. Vi hen the stay Wires pass over there they turn backward, and Weighted arms 1.52 secured to the roel; shaft 151 restore them to their normal position as soon as the sta Y rfires have passed.

The two outside line wires are crimped to give them tlle required elasticity, and to make them compare in length with the intermediate wires 'which are shortened by being iollowing crimping mechanism o? which one iseloeated on each side of the niaenine, and normally below the adjacent outside line wire.

A vertical tubular support lo? bas a yoke 178 on its lower end. This yoke has a verte Cal slot 178 through which the shaft 2%? passes, and the entireI crimping devine sup-ported on said sl" ft. Two crimping jar: levers 163, 164, are pli'oted to the uriner end of this support and are'provided wird frirnoing iingers so placed that when the i,aws :are closed they may pass each other. 'The lower ends of' t'nese levers are pii'oted to links 170, whose lower ends are united by a pivot pin 15). This piro pin passes llnongli slots l 1&8 in the support and through a bloek "which slides therein. f1 spriin;l @within the support above that block tends to pusli it l downward and thereby to open said lrinxpingr laws. A slidingr rod 71 is also in said tuine support, its upper end bein;r sereiwd into 'said block, and its lower end projoctingbe low the supp-ort. A swinging arm 175 pivyotod to one of *he side traine members, is also pivoted to the suiiport 1(37, there )y holding' the crimping dey-ire in a substantiallyerect position. ll'hile the stay wires are being twisted, a cani 172% on shaft 37 engages with the lower end ol rod 171, and lifts the entire crimping device until the two Crimping jans are on opposite sides ol the line wire, At

this time 'ne lower end of slot iis has engaged with shalt Il?, making it impossible to bent between the iavrs 7-8, by means of the move the erimping device up anyY l'urilier.

The completed fence after passing over a guide roller 200 is wound upon' the reel, which is constructed as follows: 201 and 202 are flanged heads which are provided with short shafts mounted upon the side frame in suitable bearings. In the larger head 201 is a circular recess formed in part by a removable block 206 which is removable radially through a slot in the face of the disk. 'This removable piece is held in lace by a wedge 205, which, when remover, ermits the removal of block 206. In the 'ace of the head 202 is a circular recess, and across this recess as well as across the recess formed in part by the ,block 206, is a Adiametrical rib 207. These circular recesses are for the reception of the ends of reel roll 204 .which is made of two longitudinal separable halves. When the ends of'this roll are in the recesses of the two heads, the ribs 207 lie between these two halves and keep them separated. Y\ hen a sullicient quantityv of fence has been wound upon the central roll 204 between the heads 201 and 202, it may be removed by rst removing the wedge 205 and then removing the block 206. The end of the roll 204, which is in that particular recess, may be then removed, and in being removed, will withdraw the other end from the-head in the recess 202. `\\hcn the roller is withdrawn from these heads, the ribs 207 ol' course are withdrawn from'between the two halves of the roll whereupon said roll collapses in diameter and the two halves thereoll may readily be withdrawn trom the reel of fence A most ell'rcicnt adjunct to the felice feeding device is found in the. friction device which regulates the power ol' thc friction belt, which drives the rcel, as seen in Figs. 1' and 2, and in detail in ltig. 45.

' 153 is the belt which passes over the pullejcs 1.51 and 155, one on the main shaft and the other on the rcel shaft 156. An idler 157 which rests upon the belt is mounted upon a pin 15S, on the outer end of an arm 159. winch in t'urn is sleeved over the wristl 160 secured to the sideframe.

To make the idler more easily Imanipulated, a lever v162 is pivoted upon the frame and connected with the pulleyr pin, by means of which the pulley can be forced down upon the belt, or raised tovrelieve it from friction as desired, the nut 161 holding it wherever laced. The utility of this device is as folows: The movement of the fence'by the feed bar and its adjuncts enables the de.
